A coupling wire guide for intracorporeal procedures that may be coupled to a previously introduced wire guide, thereby permitting introduction of the coupling wire guide separately and identically in a manner that is both reliable as well as traceable. One embodiment of the wire guide includes a main body having a distal end and a tip portion connected to the distal end of the main body. The tip portion defines an axial passageway having a distal opening and a proximal opening, the passageway being sized to receive a second wire guide therein. The tip portion includes a linking member connected to the distal end of the main body to provide a secure connection between the distal end of the main body and the tip portion.
